The dap4 continues the tradition of advanced electronic devices from Data Aire for monitoring and control of computer
room air conditioning units which began in 1977. Each generation has provided more accurate monitoring information
and flexibility in controlling the unit.
The dap4 offers the definite answer for precision environmental control. The dap4 control system not only controls
and monitors temperature, humidity, airflow and cleanliness, it provides component run times, alarm history and an
automatic self-test of the microprocessor. All messages are sequentially displayed on a backlit LCD (liquid crystal
display). The dap4 can interface with a variety of building management systems (BMS).

Getting Started:
The dap4 consists of two main components: the control module and the display panel. The control module is located in the electrical panel. The display panel is remotely mounted to one of the
outer front doors. The two are connected by special telephone type cable harness (units may be
ordered with longer cables for optional remote wall mounting). Note: If used, regular telephone cable will not operate. Factory cable is required.
All data displayed on the display screen originates from the control module. The display panel
has a backlit LCD (liquid crystal display). There are six keys on the face of the display panel to
retrieve or enter settings.

SYSTEM START DELAY
After the self-test is complete, the Timed Start Delay will be displayed and will start counting down from the programmed delay time. The factory setting is five (5) seconds. The setting is programmed in Menu A – ON/OFF. The
range is from 1 to 600 seconds in 5 second increments.
BLOWER
Plug Fans – Units with plug fans have a “soft-start”. Upon completion of the Timed Start Delay, on multiple fan units,
the first fan will start. After five (5) seconds the second fan will start. The third and fourth fans (as applicable) will follow the same delay sequence.
Centrifugal Fans – The blower(s) will start upon completion of the Timed Start Delay and is programmed and wired to
run continuously during unit operation.
FUNCTIONS
Cooling, reheat, humidification and dehumidification functions are inhibited for one (1) minute after the blower(s) start.
This allows the temperature and humidity sensors to adjust.
COMPRESSOR COOLING
1. There is a five (5) minute delay between start-to-start of the same primary stage compressor. The delay will be
increased to six (6) minutes for one (1) hour following the detection of a compressor short-cycle condition even if the
compressor short cycle alarm is disabled (Menu K - Alarms and Limits).
2. There is a two (2) minute delay between stop-to-start of the same primary stage compressor.
3. There is a one (1) minute delay between stop-to-start of the same secondary unloader stage compressor or stopto-start of a second secondary unloader stage compressor.
4. Compressor staging sequence at each adjustment period:
UNITS WITH STANDARD (DUAL) SCROLL COMPRESSORS
Compressor “ON” sequence (Increasing Temperature)
Cool 1 ON at Temperature Setpoint + Temperature Deadband
Cool 2 ON at Temperature Setpoint + Temperature Deadband + y°F
Compressor “OFF” sequence (Decreasing Temperature)
Cool 2 OFF at Temperature Setpoint + y°F
Cool 1 OFF at Temperature Setpoint
UNITS WITH OPTIONAL TANDEM SCROLL OR SEMI-HERMETIC COMPRESSORS
Compressor “ON” sequence (Increasing Temperature)
Cool 1 ON at Temperature Setpoint + Temperature Deadband
Cool 2 ON at Temperature Setpoint + Temperature Deadband + y°F
Cool 3 ON at Temperature Setpoint + Temperature Deadband + 2y°F
Cool 4 ON at Temperature Setpoint + Temperature Deadband + 3y°F
Compressor “OFF” sequence (Decreasing Temperature)
Cool 4 OFF at Temperature Setpoint + 3y°F
Cool 3 OFF at Temperature Setpoint + 2y°F
Cool 2 OFF at Temperature Setpoint + y°F
Cool 1 OFF at Temperature Setpoint
Note: y = “stage to stage” which can be changed in MenuB-Setpoints; default value is 0.3
5. If the temperature drops below the setpoint during an adjustment period, all compressors turn OFF at once.

CHILLED WATER COOLING
Chilled water valve “opening” sequence (Increasing Temperature)
1. The chilled water valve proportionally opens 10% for each 0.1°F above the temperature setpoint plus temperature
deadband.
2. The chilled water valve responds to a change of the return air temperature after each adjustment period. When
a change is made to the setpoint, the chilled water valve will delay its response for five (5) minutes, after which it will
respond to each adjustment period.
If the current temperature is higher than the temperature at the last adjustment period, the following sequence will
determine the new valve position:
Current Temperature = Setpoint + Deadband + 0.0°F =
Current Temperature = Setpoint + Deadband + 0.1°F =
Current Temperature = Setpoint + Deadband + 0.2°F =
Current Temperature = Setpoint + Deadband + 0.3°F =

Chilled water valve “closing” sequence (Decreasing Temperature)
1. The chilled water valve proportionally closes 10% for each 0.1°F below the temperature setpoint plus 1.0°F.
2. The chilled water valve responds to a change of the return air temperature after each adjustment period. When
a change is made to the setpoint, the chilled water valve will delay its response for five (5) minutes, after which it will
respond to each adjustment period.
3. If the current temperature is lower than the temperature at the last adjustment period, the following sequence will
determine the new valve position:
Current Temperature = Setpoint + 1.0°F = 100% Position Open
Current Temperature = Setpoint + 0.9°F = 90% Position Open
Current Temperature = Setpoint + 0.8°F = 80% Position Open
Current Temperature = Setpoint + 0.7°F = 70% Position Open
Current Temperature = Setpoint + 0.6°F = 60% Position Open
Current Temperature = Setpoint + 0.5°F = 50% Position Open
Current Temperature = Setpoint + 0.4°F = 40% Position Open
Current Temperature = Setpoint + 0.3°F = 30% Position Open
Current Temperature = Setpoint + 0.2°F = 20% Position Open
Current Temperature = Setpoint + 0.1°F = 10% Position Open
Current Temperature = Setpoint + 0.0°F =
0% Position Open
4. If the temperature is consistently rising, the valve will open accordingly at each adjustment period. Likewise, if
the temperature is consistently falling, the valve will close accordingly at each adjustment period. However, if the
temperature changes directions, the temperature must change the amount of the deadband before the valve will be
repositioned. The temperature can slowly drift back and forth within a deadband window at any point in the adjustment period without a valve position change.
ENERGY SAVER and AUXILIARY CHILLED WATER COOLING
1. Energy Saver/Auxiliary Chilled Water Cooling will be available whenever the incoming water (or water/glycol) supply is below the Energy Saver/Chilled Water temperature setpoint (Menu B – Setpoint).
2. The Energy Saver/Auxiliary Chilled Water Cooling mode will operate only in a two (2) degree range. The range
is between the return air setpoint plus deadband and two (2) degrees. If the temperature rises above this range, the

Energy Saver/Auxiliary Chilled Water Cooling will be inhibited for the amount of time set in Menu J, “Energy Saver
Lockout Time” and DX (Direct Expansion) cooling will take over. After the amount of time set in Menu J – Factory Settings, “Energy Saver Lockout Time”, it will try Energy Saver/Auxiliary Chilled Water Cooling again.
3. The chilled water valve proportionally opens 10% for each 0.1°F above the temperature setpoint plus temperature
deadband.
4. The chilled water valve responds to a change of the return air temperature after each adjustment period. When
a change is made to the setpoint, the chilled water valve will delay its response for five (5) minutes, after which it will
respond to each adjustment period.
5. If the temperature is consistently rising, the valve will be opened more at each adjustment period. Likewise, if the
temperature is consistently falling, the valve will be closed more at each adjustment period. However, if the temperature movement changes directions, then it must change the amount of the deadband before the valve will be repositioned. The temperature can be slowly drifting back and forth within a deadband window at any point in the adjustment period and no valve changes will be made.
6. If the current temperature is higher than at the last adjustment period, the following sequence is used to determine
the new valve position:
Current Temperature = Setpoint + Deadband + 0.0°F = 0% Position Open
Current Temperature = Setpoint + Deadband + 0.1°F = 10% Position Open
Current Temperature = Setpoint + Deadband + 0.2°F = 20% Position Open
Current Temperature = Setpoint + Deadband + 0.3°F = 30% Position Open
Current Temperature = Setpoint + Deadband + 0.4°F = 40% Position Open
Current Temperature = Setpoint + Deadband + 0.5°F = 50% Position Open
Current Temperature = Setpoint + Deadband + 0.6°F = 60% Position Open
Current Temperature = Setpoint + Deadband + 0.7°F = 70% Position Open
Current Temperature = Setpoint + Deadband + 0.8°F = 80% Position Open
Current Temperature = Setpoint + Deadband + 0.9°F = 90% Position Open
Current Temperature = Setpoint + Deadband + 1.0°F = 100% Position Open
7. The chilled water valve proportionally closes 10% for each 0.1°F below the temperature setpoint plus 1°F.
8. If the current temperature is lower than at the last adjustment period, the following sequence is used to determine
the new valve position:
Current Temperature = Setpoint + 1.0°F = 100% Position Open
Current Temperature = Setpoint + 0.9°F = 90% Position Open
Current Temperature = Setpoint + 0.8°F = 80% Position Open
Current Temperature = Setpoint + 0.7°F = 70% Position Open
Current Temperature = Setpoint + 0.6°F = 60% Position Open
Current Temperature = Setpoint + 0.5°F = 50% Position Open
Current Temperature = Setpoint + 0.4°F = 40% Position Open
Current Temperature = Setpoint + 0.3°F = 30% Position Open
Current Temperature = Setpoint + 0.2°F = 20% Position Open
Current Temperature = Setpoint + 0.1°F = 10% Position Open
Current Temperature = Setpoint + 0.0°F = 0% Position Open

until the return air temperature rises to the temperature setpoint. Compressor short-cycle time will not be violated.
3. If dehumidification is programmed for “No Reheat Limits” it will remain ON until the humidity setpoint is reached. In
this mode dehumidification has priority and overcooling is disregarded. The reheat sequence will remain the same.
4. If dehumidification is programmed for two (2) compressors, with or without reheat limits, only one (1) compressor
will be allowed if reheat is required.
5. There is a one (1) minute delay between stop-to-start of dehumidification. Compressor short-cycle time delay will

FAN SPEED CONTROL FOR CHILLED WATER (CW) UNITS WITH PLUG FANS
Seven (7) fan speed control modes can be selected for units with plug fans. The control modes are programmable
(See Menu J – Factory Settings: Fan Settings). Any one of the following may be chosen:
1.
2.
3.
4.
Const Speed (Constant fan speed)
BMS Speed (Fan speed controlled by BMS)
Vlv Pos Speed (Proportional fan speed control based on the CW valve action)
Air Pressure (Constant air static pressure)
1. Const Speed (Constant fan speed): On units where constant design fan speed is required (i.e. standard plug fan
configuration), a value based on percentage of fan speed is entered into the dap4 through Menu J – Factory Settings (Const Speed). The adjustable range is 60 – 100%, which results in an analog output of 6 VDC to 10 VDC.
In this mode the fan will start and operate at the selected fan speed.
2. BMS Speed (Fan speed controlled by BMS mode) – Allow users to control the fan speed by BMS. The range for
this fan speed is from 30-100%. In this mode, “CW Speed” and the “Modulating Max” and “Modulating Min” must
be configured.
When the fan starts, it will operate at the front panel programmed constant fan speed (“CW Speed” is selectable between 60-100%). It will modulate to the BMS programmed fan speed when a network communication (with the BMS)
is established.
If either the reheat or humidifiers are used, the maximum fan speed setting is required and will be used as the maximum limit fan speed. If the reheat or humidifier is required while the fan speed is commanded by the BMS to a value
that is lower than the maximum fan speed, the fan speed will automatically increase to the maximum speed. The fan
speed will revert to the BMS programmed fan speed when the unit stops calling for reheat or humidifier.

SPACE CONTROL CONDITIONS CAUSED BY THIS SELECTION.
3. Vlv Pos Flow (Proportional fan speed control based on the CW action mode) – Allow users to automatically control
the fan speed based on the CW valve action. In this mode, “CW Speed” and the “Modulating Max” and “Modulating
Min” must be configured. “Modulate Max” is the maximum allowable fan speed (range 70 – 100% of fan capability).
“Modulate Min” is a minimum fan speed (as low as 40% of the maximum allowable fan speed).
Example: For a fan with a speed capacity of 1750 RPM, a maximum allowable programmed fan speed of 1501 RPM
is chosen. At this RPM, the maximum speed is 86% of the rated RPM (1501/1750 = 85.77%). If 60% is chosen for
minimum fan speed menu J (Factory settings), the minimum programmed fan speed will be 901 RPM (1501 x .60 =
901) and the fan capability is 52% (901/1750 = 51.49%).
When the fan starts, it will operate at the minimum fan speed. As the chilled water valve opens, the fan speed will
modulate proportionally based on the chilled water valve action from the programmed maximum fan speed (when the
chilled water valve is fully open).
The fan will operate at the maximum fan speed when the unit calls for reheat or humidification.
4. Air Pressure (Constant static pressure control mode): In this mode, the controller will automatically adjust the fans’
speed in order to achieve a desired differential pressure. A differential pressure transmitter is required to installed and
configured (Menu L: Configure I/O). When this option is selected, a separate page called Static Fan Pressure will
show up. Users need to enter the “CW Speed”, “Modulate Max”, “Modulate Min” on the Fan Settings page and configure the “Setpoint”, “Band” and “Int time” on the Static Fan Pressure page (Menu J: Factory Settings)
When started in this mode, the fan will first operate at the programmed constant fan speed for 5 minutes. After the
initial 5 minutes, the fan will proportionally increase or decrease the speed to maintain a constant static pressure
setpoint as follows:
• If the measured differential pressure is less than the differential pressure setpoint 1% for each response
time period (“Int time”) until the differential pressure setpoint is reached (fan speed cannot exceed the
maximum speed).
•
If the measured differential pressure is greater than the differential pressure setpoint plus differential pressure band, the fan speed will decrease 1% for each response time period until the differential pressure
setpoint is reached (fan speed cannot be lower than minimum fan speed).
•
Otherwise, fan speed will remain constant
FAN SPEED CONTROL FOR DIRECT EXPANSION (DX) UNITS
Two (3) fan speed control modes can be selected for units with plug fans. The control modes are accessible through
Menu J – Factory Settings. Either of the following may be chosen:
1. Const Speed (Constant fan speed)
2. BMS Speed (Fan speed controlled by BMS)
3. Air Pressure (Constant air static pressure)
1. Const Speed (Constant fan speed): On units where constant design fan speed is required (i.e. standard plug fan
configuration), a value based on percentage of fan speed is entered into the dap4 through Menu J – Factory Settings
(Const Speed). The adjustable range is 70 – 100%, which results in an analog output of 7 VDC to 10 VDC. In this
mode the fan will start and operate at the selected fan speed.
2. BMS Speed (Fan speed controlled by BMS mode) – Similar to BMS Speed fan speed control for Chilled Water
units.
3. Air Pressure (Constant air static pressure speed control) - In this mode, the controller will automatically adjust the
fans’ speed in order to achieve a desired differential pressure. A differential pressure transmitter is required to installed
and configured (Menu L: Configure I/O). When this option is selected, a separate page called Static Fan Pressure will
show up. Users need to enter the “DX Speed” (constant speed), “Modulate Max”, “Modulate Min” on the Fan Settings
page and configure the “Setpoint”, “Band” and “Int time” on the Static Fan Pressure page (Menu J: Factory Settings)
The fan speed control logic is similar to that of fan speed control by Air Pressure for Chilled Water units. However, an
optional discharge sensor is required for this mode. The discharge sensor will be used as a safety freeze thermostat.
If the discharge temperature falls below the discharge temperature limit setting, the fan will increase to the maximum
allowable programmed speed until the discharge temperature rises above the discharge temperature limit for 15 minutes.

Manual Override Switches
For testing and during start-up each Data Aire gForce unit is provided with manual override slide
switches. There are seven slide switches. One for each of the following functions:
Water Valve
Fan Speed
Humidifier
Heat 1
Cool 2
Cool 1
Blower
All automatic control is disabled but the safety switches remain functional. Simply slide the manual
switches to energize the blower, compressors, humidification, reheat and other functions.
The fan speed of the EC (Electronically Commutated) motor can be adjusted from 0 – 10 volts by
adjusting the potentiometer at the left of the Fan Speed switch. The fan will turn 10% for each volt
adjustment. One volt equals 10%. At ten volts the motor is at full speed.
Warning: Do not leave the unit in manual override. Slide the switches to the OFF position when
completing testing and/or start-up. An alarm will be activated if units are left in the ON position.
